Instead of your mate saying you're drunk and recommending an Uber, a packet of Tostitos can now do it for you. 

Chip maker Frito-Lay, which makes Tostitos, has designed a bag that acts as a breathalyser, indicating whether it's safe for you to drive or not. 

The process is easy and requires the person to blow on the front of the bag. If any alcohol is detected, the sensor turns red and forms the image of a steering wheel, along with an Uber code and a 'Don't drink and drive' message. 

If you're safe to drive, it'll light up green, showing results were below the driving limit. 

But Lawrence Police in Kansas has ridiculed the idea, tweeting that if anyone needs the bag to tell them they're drunk "for the love of all that is holy, do not drive".

It has since been retweeted more than 21,000 times.

The 'Party Safe' bag will be released in time for the largest snacking and drinking event - Superbowl Sunday - on February 6. 

"Our goal is to remove 25,000 cars from the roads that Sunday evening," Jennifer Saenz, Frito-Lay's chief marketing officer, told Adweek.

In 2015, 45 people were killed in drink driving accident on Superbowl Sunday, which was nearly half of all traffic fatalities that day, according to the National Highway Traffic Safety Administration.
